Creating a Digital 3D Model of the Dental Cast Using Structure-from-Motion Photogrammetry Technique

International Journal of Online and Biomedical Engineering (iJOE), 2023
Photogrammetry is a technique used to obtain a reliable database of any physical object, by creating a digital 3d model using multiple photos taken at different angles around the object. Recently, several fields have used this technique to build digital 3D models, such as topography, architecture, engineering, and medicine.
